In a recent research study published in Nature Communications, neurobiologist Sara Wilson of Umeå University found that during embryonic development different parts of the nerve cell are important for guiding other nerve cells into their physical positions.http://medicalxpress.com/news/2015-05-nerve-cells.html

Physicians previously attributed this regression to depression or early-onset Alzheimer's, and it has not responded to treatments. Now, a researcher at the University of Missouri has found that Catatonia, a treatable disorder, may cause regression in patients with Down syndrome. Individuals with regressive Down syndrome who were treated for Catatonia showed improvement, the researcher found.http://medicalxpress.com/news/2015-05-regression-individuals-syndrome.html

Now, a study from the University of Missouri has found evidence to contradict this speculation. It is the first study to test the effects of violent video games on aggression in adults with autism spectrum disorder.http://medicalxpress.com/news/2015-04-violent-video-games-linked-aggression.html

Babies whose mothers take the epilepsy drug valporic acid (VPA) during pregnancy, for example, appear to have an elevated risk of developing an autism spectrum disorder. In a new study, scientists who developed a tadpole model of this exposure directly observed deleterious effects on brain physiology and behavior. Understanding that connection could provide scientists with the opportunity to discover how to stop it.http://medicalxpress.com/news/2015-02-tadpole-links-drug-exposure-autism-like.html

A study published by Cell Press October 9th in the American Journal of Human Genetics shows that neurodevelopmental disorders caused by distinct genetic mutations produce similar molecular effects in cells, suggesting that a one-size-fits-all therapeutic approach could be effective for conditions ranging from seizures to attention-deficit hyperactivity disorder.http://medicalxpress.com/news/2014-10-multiple-neurodevelopmental-disorders-common-molecular.html
